All that may be true, Gene. But don't Maxwell's
equations obey the superposition principle?
What does Maxwell say happens when we superpose
two EM waves out of phase such that destructive
interference occurs? What does Maxwell say
about the energy "lost" to destructive
interference? Where did it go?

Are intensity calculations utterly inadequate
for exploring the details of low resolution
transmission lines? :-) If the intensity
(power) calculations enumerated in the s-
parameter analysis description are utterly
inadequate, why are they used so often?

Cecil,

Changing the topic again? So soon?

You made a claim about optical physicists. I pointed out that your claim
is simply not correct. You then start babbling about low resolution
transmission lines. What a surprise!

You seem to be going back and forth about the utility of bringing optics
into the discussion on antennas and transmission lines. I doubt that
many here would expect different physical principles to apply to the two
wavelength regimes. I wonder if there might be a practical reason why
the preferred computational techniques are somewhat different?

The physics does not change, but the mathematical convenience does
change. Yes, that seems to be a recurring theme from me.
